a) Demand is instantaneous

b) Demand is marginal

c) Demand is inelastic

d) Demand is elastic

e) Demand is unit elastic

2. In a sample of 50 individuals, 7 said they would pay up to $100 for World Series Tickets. Of the people surveyed, what is the probability that any one randomly selected, would pay up to $90 for this ticket?

a) Less than or equal to 14%

b) 14%

c) 86%

d) Area of probability functions under zero to $90

e) None

3. Definite Integral with 3 on top (ending) and 2 on the bottom (start)

.

a) About 3.43

b) About 8.02

c) 4.75

d) None

4. The range of potential revenue from a project is: negative $200,000 to positive $400,000 (-2 less than or equal to x, which is less than or equal to 4). The probability density function of the potential outcome is represented by: f(x) = -0.0208x^2 + 0.417x + 0.208. From this data, what is the probability that your revenue will be $300,000 or less?

b) 100.058

c) 0 .25415

d) 0 .85754

e) 0 .74158

b) Limits of additions and subtraction can not be split.

c) The minimum and maximum of a constant vary w/ the probability

d) The limit of a constant is that constant

e) The curve of a constant function is always concave.

6. If you set a supply function equal to demand function, what are you representing?

a) Equilibrium differential

b) Equilibrium price and quantity

c) Consumer surplus

d) Producer surplus

e) Extra revenue
